Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.

rwilson504 Skill Dataverse Classic Analyze 2Gap-analyze an existing Dataverse Classic Workflow against new requirements and flag risky patterns. Use when user says "I have new requirements, what needs to change", "does this workflow meet this spec", "gap analysis", "review this workflow", "what is wrong with this workflow", "why does this loop", "is this workflow going to run away", "audit this workflow", or supplies a requirements document alongside a `.xaml`. Produces a requirement-by-requirement verdict plus a change plan, and checks the documented failure modes: infinite-loop protection (the 16-in-a-short-window rule), hierarchical Under / Not Under operator behavior, scope and run-as mismatches, and MS Learn best-practice violations. Do NOT use for plain summarization (use dataverse-classic-read) or for applying the changes (use dataverse-classic-write).
